One error after another when switching. First misinformation about mt tariff....discussed it with them and that looked to be resolved. I registered with their priority service department and informed them that obtaining meter readings would be near to impossible for me (due to where my gas meter is located it would involve me crawling along the floor) My switching date was the 12th April and they requested opening meter readings, which with much difficulty I obtained and entered on my account. Last week I noticed a message on my account stating I did not enter my opening readings and the time to do this had expired and they would use estimated reads. Due to my anxiety I can't cope with these changes, so I contacted EDF and their live chat person said they were going to sort it. When I logged in later that day it was asking me for opening reads again. I contacted EDF and was told to ignore that as my switch was not complete and someting had gone wrong. This really set my anxiety off so I contacted their complaints department and was told they WERE using the reads I gave them on the 12th and everything was going as it should. Saturday (24th) I logged in and noticed it again said I was too late in giving my opening meter reads, as they were closed I initially shrugged it off and trusted what they said thet they were using the reads I gave. BUT then on the 25th I got a notification from my previous supplier that my final bill was ready and upon checking this I noticed they did use estimated reads. This caused such an anxiety reaction I had to take strong medication and it caused severe worries. This morning I made EDF aware of all this and to say they could care less was an understatement. They did not care at all about how they caused me 2 anxiety attacks, nor the physical pain they caused in obtaining their meter reads. Why do this if you are not going to use the reads. All they come up with is that the reads are within the acceptable tollerance, interestingly the reads are in THEIR favour, with a higher unit cost than my previous tariff. If it was up to me I would leave EDF straight away. If you have any disability do yourself a favour and stay away.
